Acorn Communicator
I suppose by this point the Archimedes was well under way, so we see that individual language and service ROMs in earlier Acorns have given way to what we recognise as the modular layout of the operating system and its component parts. The help listing is in essence a listing of the modules in the MOS ROM, with additional information on command syntax, and module version numbers. Several of the modules listed match the names found in an Archimedes.
